Had many boot entries on UEFI,made os x boot very slow,so reseted UEFI/BIOS and did this exercise and VOILA.never thought this efivar would help.used Mint18 distro, now boots up in a flash.:headbang:
Ok my bad. i typed in the boot flage wrong but thank you for the help abot the audio, got the usb working some how,:headbang:Thank you so much for the information about HDMI Audio some how missed that when googled.
I used unibeast and boot flags -x -no -fp when install from usb. after that used clover config.Yosemite up and running two days now, still some usb ports won't work and no audio but haven't tested hdmi yet, if the audio works from there. so do anybody understand what to pick in clover...
